Hi All,
I need to find the external/internal/net wind pressure coefficients for vertical walls that are concave on plan. I would have thought intuitively that wind on such a concave wall would be subject to an increased pressure, as for continuation purposes its path after hitting the wall in...
Thank you both for your responses.
@KootK I also think this is considering the amount of reinforcement in the critical area (d/2) from face - however with what I have derived above I still don't see how this equation should have s/d instead of s/0.5d when you consider it from first principles...
Hi all,
I'm doing some punching shear checks for a series of columns acting on a 1.0m base slab for a deep underground metro station.
The contribution of stirrups or links is given by S11.4.7.2 in ACI318-11(M), or equivalent 22.6.7.2 in ACI318-19(M) etc.
As the applied shear stress (vu) is...
